VALVE.

1' b all whom it may concern:

lie it known that I, FRANK M. Asnmcv, a citizen of the United States,residing at (53 Central Place, Brooklyn, in the county of Kings andState of New York, have 111- vented certain new and useful Improvementsin Valves, of which the following is a full, clear, and exactspecification.

This invention relates to valves and its objoct is to provide a simpleand eflicient c011- struction of that type of valve wherein the valveseat can be removed for grinding or cleaning, or for replacement by anew seat.

A further object is to provide a construction wherein the interior ofthe main valvebody will not require an exact finish by reason of theemployment of a separate interior part or parts involvin the removablevalve seat, and the desired nish.

\Vith the above and other purposes in view, the novel valve comprehendsthe improved construction set forth in the subsequent detaileddescription.

In the accompanying drawings forming part of this specification,-Figure1, is a sectional view of a valve embodying my invention. Fig. 2, is aview of similar character illustrating a modification of a valve. Figs.3 and 4:, are plan and vertical sectional views respectively, of theseating proper. Figs. 5 and 6, are sectional and plan viewsrespectively, of a modified form of the inner ring seating.

1, represents the body or casing having the usual inlet and outletopenings 2 and 3, interiorly threaded for the engagement of the pipes 4and 5, the chamber within the casing being divided by a wall 6,containing the seat opening 7. Upon one side of the wall 6, is thebonnet opening 8, in which is fitted the cylinder 9, the latter having alower annular portion resting on the wall 6, and surrounding the opening7.

It will be notedthat the wall 6, im mediately surrounding its opening 7,cmbodies an annular raised seat 6 the lower end portion of the cylinder9, containing in its under side, an annular groove which permits saidportion to fit over said raised seat 6 with the circular surface formingthe opening in the said portion flush with the corresponding surface inthe wall 6. The lower annular portion of the cylinder, also presents atits upper side a raised seat 10. It will be advantageous to interpose aring 12 of packing material between the seat 6,

and the grooved portion of the cylinder resting thereon, as suchemployment of the packing will obviate the necessity for accuratelymachining these parts.

13 refers to the usual cap or bonnet held in engagement with thevalve-body either by screw threads 14.- as shown in Fig. 1, or by meansof an independent threaded ring 15, as indicated in Fig. 2, the cap ineither i11- stance acting to hold the cylinder down upon the wall 6,either by bearing directly upon the upper end of said cylinder orthrough an interposed ring 16, of packing material. The opening 17, isin one side of the cylinder to furnish the requisite passageway. Thevalve stem may be adjustable in the cap 13, by threads 20, or otherwise.If preferred, the cylinder 9, may comprise a plurality of parts, Fig. 5,illustrating a construction wherein the seat 10 is in one piece 35, andthe body of the cylinder in another piece 36.

It will be seen that when the cylinder and its seat are removed forrepair or for other purposes, the valve can still be used as thecharacter of the raised seating 011 the wall 6, and the lower face ofthe valve are such that the said valve will squarely, adequately andefliciently secure a bearing on said seating, the tightness of the jointbeing au mented by the presence of a ring 19, of yielc ing n1aterial inthe underside of the valve.

With a view of further preventing any turning of the cylinder and itsseat, the cylinder body externally contains a vertical groove 22, whichas the cylinder is introuced in position, is adapted to have enagedtherein a lug 23, integrally projecting from the contiguous part of thevalve body.

The construction set forth is simple, comparatively inexpensive andeasily maintained in good condition.

Having now described my invention, what I claim as new and desire tosecure by Letters Patent, is-

1. In a valve of the character described, the combination of a bodyportion having an internal lug at one side, said body portion alsocontaining a dividing wall presenting an opening and raised ring seatsurrounding said openlng, a cyhnder with a groove engaged by saidbody-lug and with a lower portion embodying a raised ring seat andcontaining an under groove for receiving the seat of the dividing wall,the surface forming the opening in said lower portion being flush withthe corresponding surface in the wall, a ('31) confining said cylinderand holding the lower seat portion in bearing engagement with thedividing wall and a valve Htclll guided through the cap and carrying avalve for coaetion with either of said seats.

:2. In a valve of the character described, the combination of a bodyportion liavii'ig an internal lug at one side, said body portion alsocontaining a dividing wall presenting an opening and raised ring seatsurrounding said opening, a cylinder with a groove engaged by .said bodylug and with a lower portion enilmdying a raised ring seat andcontaining an under groove for receiving the seal of the dividing wall,the surface forming the opening in said lower portion being {lush withthe correspondin surface in the wall, a cap confining said cy inder andholding the lower seat portion in bearing engagement with the dividingWall, and a valve Hl'Clll guided through the ca 3 and carrying a valvefor coaction with eitier of said ring seats, said valve having ayielding face.

In testilnonv whereof I afiix my signature, in presence of twowitnesses.
